Make use of a random number generator to generate a list of 500 three-digit numbers. Create a sequential list FILE of the 500 numbers. Artificially implement storage blocks on the sequential list with every block containing a maximum of 10 numbers only. Open an index INDX over the sequential list FILE which records the highest key in each storage block and the address of the storage block. Implement Indexed Sequential search to look for keys K in FILE. Compare the number of comparisons made by the search with that of the sequential search for the same set of keys.Extend the implementation to include an index over the index INDX.
Write a recursive function to recursively print the file list returned by os.listdir().
def analyze_file (filename: str, pos_words: List [str], neg_words: List [str]) -> Given the name of a file, a list of positive words (all in lowercase), and a list of negative words (all in lowercase), return some interesting data about the file in a tuple, with the first item in the tuple being the positivity score of the contents of this file, and the rest of the item: being whatever else you end up analyzing. (Helper functions are highly encouraged here.) How to calculate positivity score: For every word that is pos itive in the file (based on the words in the list of positive words) add 1 to the score. For every negative word (based on the list of negative words), subtract 1 from the score. Any neutral words (those that do not appear in either list) do not affect the score in any way. pass
Write the program that allows the user to sort using the Merge Sort and Quick Sort. The program should be able to read in data from a binary file (1000000numbers). The first element of the binary file will be used to tell how many elements to read in. Once all the data has been read in, the program should sort the data. The user should be able to choose which algorithm to use to sort the data. The program should print the time before and after the sort. The last part of the program should prompt the user for a lower and upper bound. These two values should then be used to decide how much and which part of the array will be display. You should test all of the sorts on each of the data files. There are a number of files (10numbers.zip, etc.) of increasing size that you can utilize for testing purposes. Continue to add a a justification of the difference between the run times of each sort when compared to those you're reported on earlier. Include the screenshots of the…
Here is the iterative implementation of binary search: For each call to binary_search below, indicate how many times the code inside the while loop will execute. animals = ["aardvark", "cat", "dog", "elephant", "panda"] 1. binary_search("elephant", animals) 2. binary_search("dog", animals) 3. binary_search("anteater", animals)
Collapse positive integer intervals def collapse_intervals(items): This function is the inverse of the previous problem of expanding positive integer intervals. Given a nonempty list of positive integer items guaranteed to be in sorted ascending order, create and return the unique description string where every maximal sublist of consecutive integers has been condensed to the notation first-last. Such encoding doesn’t actually save any characters when first and last differ by only one. However, it is usually more important for the encoding to be uniform than to be pretty. As a general principle, uniform and consistent encoding of data allows the processing of that data to also be uniform in the tools down the line. If some maximal sublist consists of a single integer, it must be included in the result string all by itself without the minus sign separating it from the now redundant last number. Make sure that the string returned by your function does not contain any whitespace…
Write a program that first reads in the name of an input file and then reads the input file using the file.readlines() method. The input file contains an unsorted list of number of seasons followed by the corresponding TV show. Your program should put the contents of the input file into a dictionary where the number of seasons are the keys, and a list of TV shows are the values (since multiple shows could have the same number of seasons). Sort the dictionary by key (least to greatest) and output the results to a file named output_keys.txt. Separate multiple TV shows associated with the same key with a semicolon (;), ordering by appearance in the input file. Next, sort the dictionary by values (alphabetical order), and output the results to a file named output_titles.txt. Ex: If the input is: file1.txt and the contents of file1.txt are: 20 Gunsmoke 30 The Simpsons 10 Will & Grace 14 Dallas 20 Law & Order 12 Murder, She Wrote the file output_keys.txt should contain: 10: Will…
